problems with caching DOP networks

Recommended Posts

Hi,

i've been learning how to cache DOP networks ( part of a greater project )

currently got to work by using the DOP i/o node to render out a specific frame range,

But when i try to import in that cached data using a file node, i realize that there isnt any color information on it.

For example, using pryo FX i was able to cache a frame sequence, but when i bring it back in, i get a grayscale sequence.

anyone knows if im missing a step along the way?

thanks.

Color isnt a property of the simulation, its just a visualization of the fields density, temperature and heat.

You can recreate it if you want with a volume visualize SOP

Dop I/o node is designed to make this easier.

Just add a field to import and name it "Visualization"

Cheers!

Thanks! that worked out very well.

One question though, is it possible to set it up so that Houdini automatically caches a simulation after you change parameters on it?

a possible scenario is setting this up as a digital asset so that artists can just change those parameters ; bigger fire, no smoke,etc, and after changing it, Houdini automatically caches it?
